Let’s talk EPC 2.

EPC rating
EPC rating diagram sample

In the first part of the article we tried to provide a general overview about Energy Performance Certificate (EPC). Today we are going to explain what different ratings mean, and how they affect our everyday life.

To demonstrate these effects, we chose a home with the most common EPC rating on the British market. The diagram below belongs to such a house.

diagram about-uk-domestic-EPC-rating

The EPC rating is 68 (level D). Most homes in the UK have a rating between 55 and 75, so we can say this example represents an average UK home. Now is this value good or not? I know I said this was an average value, so I might shock a few readers now when I say this value is very low. To tell you the truth only 2% of the British homes have a level B or higher rating.

Having today’s technologies and materials at our disposal it seems to me that this value is just not good enough. Although the climate varies on a large scale throughout Europe (think about the Mediterranean, Greece, Spain, Portugal and the northern countries such as Norway or Sweden) they manage to have a better overall rating in domestic EPC rating than the UK, regardless of their climate. This is because of the physical features of the buildings, the materials and technologies used, therefore the operations of the buildings are much more economical there (average EPC rating in Europe 75-80, in Germany this value is 85). Sadly the UK is significantly behind these countries in terms of domestic energy consumption.

The importance of thermal insulation started to become a factor in Europe since the ‘70s, whereas in the UK, energy efficient building technologies have only just started to be of high demand.

This results in quite significant arrears. We can still catch up to the leading European countries (in terms of high EPC rating domestic buildings), but we have to consciously design the new buildings and also plan the refurbishment projects.

The meaning of EPC rating 68:eco EPC rating A

  • cold, draughty floor
  • damp house
  • mould occurrence in corners, around windows, behind cupboards or in the bathroom – unhealthy environment
  • the changes in the outer temperature is perceptible inside the house even next to constant heating
  • high energy bills, high pollution emission

These conditions can easily be improved by professional diagnostics and the usage of modern building materials. Upgrading the windows to double-glazed or triple-glazed will not be sufficient on its own (it is a start nonetheless). To upgrade your house’s EPC rating to level “B” is easily achievable if you plan your next refurbishment project thoroughly and energy consciously – and it does not have to cost more!

How is this possible? What are the costs and how quickly will such an investment show financial return? We will elaborate these in our next article.

As usual, please feel free to share your comments, own experiences or relevant stories you may have.

Let’s talk EPC 1.

What does EPC mean?

EPC rating 1

In this article we will try to help you understand what EPC means furthermore what it means in regards to your property. It is the mandatory document that goes with every property sale; EPC stands for Energy Performance Certificate.

It basically shows you how economical a building is. But what does it tell you exactly?

It is a classification that is based on a pre-determined scale (A – G, “A” being the most economical category). The categories are determined by direct measurable factors and indirect calculations.

The two most important factors are:

  • The measure of energy required to maintain a certain temperature inside the building
  • The thermal storage capacity of the building (calculated from its physical features)

These two factors are absolutely independent from one another. We can maintain 20°C in a room by either

  • Little usage of the heating system, but in a building with excellent thermal storage capacity
  • Or with massive energy consumption (constant heating) in a poorly insulated building

EPC illustration

In both cases we would be sitting in a 20°C – room; so the result would be the same, yet what a difference in the energy consumption.

But the biggest difference is this: Let’s assume we turn down the heating in the living room for the night. In the first case (well-insulated room, excellent thermal storage capacity, high EPC ranking), not only, will the air  remain a pleasant 20°C in the morning, but also all the solid objects (floor, walls,  furniture, etc.) will not get cold. Whereas in the second case (poor insulation, poor thermal storage capacity, poor EPC ranking), we will definitely need a sweater till we have our first tea in the morning.

We are yet to highlight all the financial benefits that you can enjoy by having an economical home, with high EPC ranking. You can read about the costs of such an investment and the break-even time in our next article. Also we will explain the meaning of the different categories, e.g. what it means to have a home that is classed “D” in its Energy Performance Certificate.
